pub struct ScsiHost { /* fields omitted */ }

Fetch and modify SCSI host parameters.

Methods

impl ScsiHost

pub fn active_mod(&self) -> Result<String>

pub fn can_queue(&self) -> Result<i32>

pub fn host_busy(&self) -> Result<u8>

pub fn link_power_management_policy(&self) -> Result<String>

pub fn set_link_power_management_policy<'b>(
    &self,
    profiles: &[&'b str]
) -> Result<&'b str>

Sets the power management profile for this SCSI host.

Multiple profiles are given, and each profile is tried until one succeeds.
